That's my favorite Batman, but it's probably because I was like 12 when it came out and it was hugely marketed. Plus Prince did the Batdance song for the movie. Shit was dope as fuck.
But anyway, Michael Keaton was great as Batman. Jack Nicholson as the Joker was excellent, too. I never liked George Clooney or Val Kilmer as Batman. Christian Bale was OK. Affleck sucked as Batman but was da bomb in Phantoms, yo. Haven't seen the newest ones yet.
